Which of the following is NOT a role the CLS may be expected to do while staging a casualty?

The most appropriate answer is that intubating any casualties with respiratory compromise is NOT a role typically expected of a Combat Lifesaver (CLS) while staging a casualty. In the context of TCCC (Tactical Combat Casualty Care), the responsibilities of a CLS include assessing vital signs, providing basic first aid, and stabilizing casualties for transport. However, advanced interventions such as intubation are reserved for more highly trained medical personnel, such as medics or paramedics, who have the necessary skills and training to perform such procedures safely and effectively.

By focusing on the key responsibilities of a CLS, it becomes clear that their role is more about immediate and basic care rather than advanced airway management, which is why the option regarding intubation does not align with typical CLS duties.
